Answer:

(b) is used in Traceroute

(d) is used by Ping

Explanation:

ICMP is the short form of Internet Control Message Protocol. It is a protocol used by networking devices such as routers to perform network diagnostics and management. Since it is a messaging protocol, it is used for sending network error messages and operations information. A typical message could be;

i. Requested service is not available

ii. Host could not be reached

ICMP does not use ports. Rather it uses types and codes. Some of the most common types are echo request and echo reply.

Traceroute - which is a diagnostic tool - uses some messages available in ICMP (such as Time Exceeded) to trace a network route.

Ping - which is an administrative tool for identifying whether a host is reachable or not - also uses ICMP. The ping sends ICMP echo request packets to the host and then waits for an ICMP echo reply from the host.

ICMP is not required to solve NAT traversal problem neither does it have a new version in IPV6.

Answer: D) Sharing best practices, lessons learned and other topics in a central place where the team can collaborate

Explanation: Knowledge sharing within a team is usually an important aspect of building a strong and efficient team. Acquiring knowledge usually comes from the experience gathered from previous projects, learning, or tips learned from various sources. Therefore, sharing knowledge is always a good way to ensure that what is gained is sustained by letting others know. Sharing and sustaining knowledge is most effective when transmitted or aired to a group of people usually a team gathered in an interactive setting which allows members to freely share experience and get feedback, views, or thoughts from other collaborators.

Answer:

Here is the JAVA program to calculate volume of cuboid:

import java.util.Scanner; // Scanner class is used to take input from user

public class CuboidVol { // class to calculate volume of cuboid

public static void main(String[] args) { // start of main() function body

Scanner input= new Scanner(System.in); //create Scanner class object

// prompts user to enter length of cuboid

System.out.println("Enter the cuboid length:");

double length=input.nextDouble(); //reads the input length value from user

// prompts user to enter width of cuboid

System.out.println("Enter the cuboid width:");

double width=input.nextDouble(); //reads the input width from user

// prompts user to enter height of cuboid

System.out.println("Enter the cuboid height:");

double height=input.nextDouble(); //reads the input height from user

/* the following formula is to calculate volume of a cuboid by multiplying its length width and height and a double type variable cuboidVolume is defined to store the value of the resultant volume to it */

double  cuboidVolume= length*width*height; //calculates cuboid volume

//displays volume of cuboid and result is displayed up to 2 decimal places

System.out.printf("Volume of the cuboid (length " + length + "/ height " + height + "/ width" +width +" is: " + "%.2f",cuboidVolume);   } }

Explanation:

The formula for the volume of a cuboid is as following:

Volume = Length × Width ×  Height

So in order to calculate the volume of cuboid three variable are required for length, width and height and one more variable cuboidVolume to hold the resultant volume of the cuboid.

The program is well explained in the comments added to each statement of the program. The program prompts the user to enter the value of height width and length of cuboid and the nextDouble() method is used to take the double type input values of height length and width. Then the program declares a double type variable cuboidVolume to hold the result of the volume of cuboid. Then the last printf statement is used to display the volume of cuboid in the format format "Volume of the cuboid (length  / height  / width ) is" and the result is displayed up to 2 decimal places.

The screenshot of the program along with its output is attached.

Answer:

packet filtering

Explanation:

We can use a packet filtering firewall, for something like this, reasons because when visiting a site these types of firewalls should block all incoming traffic and analyze each packet, before sending it to the user. So if the packet is coming from a malicious origin, we can then drop that packet and be on our day ;D

Answer:

Here is the C++ program for Employee class with fields id,name and sal.

#include <iostream>  // to use input output functions

#include <string>  //to manipulate and use strings

using namespace std;   // to access objects like cin cout

class Employee {  //class Employee

/*set the name field to Abc Xyz which means set the value of Employee class name field to Abc Xyz  through setName() method and object emp */

  emp.setName("Abc Xyz");  

/*set the id field to 1234 which means set the value of Employee class id field to 1234  through setId() method and object emp */

  emp.setId(1234);

/*set the sal field to 1000 which means set the value of Employee class sal field to 1000  through setSalary() method and object emp */

  emp.setSalary(1000);    

  display(emp);  }   //calls display() method to display the Employee data

void display(Employee e) {  // this method displays the data in the Employee //class object passed as a parameter.

/*displays the name of the Employee . This name is read or accessed through accessor method getName() and object e of Employee class */

  cout << "Name: " << e.getName() << endl;  

/*displays the id of the Employee . This id is read or accessed by accessor method getId() and object e */

  cout << "ID: " << e.getId() << endl;

/*displays the salary of the Employee . This sal field is read or accessed by accessor method getSalary() and object e */

  cout << "Salary: " << e.getSalary() << endl;  }

Explanation:

The program is well explained in the comments mentioned with each statement of the program.

The program has a class Employee which has private data members id, name and sal, a simple default constructor Employee(), mutatator methods setName, setId and setSalary to set the fields, acccessor method getName, getId and getSalary to get the fields values.

A function display( ) is used to display the Employee data i.e. name id and salary of Employee.

main() has an object emp of Employee class in order to use data fields and access functions defined in Employee class.

The output of the program is:

Name: Abc Xyz                                                                                                      

ID: 1234                                                                                                                  

Salary: 1000

Answer:

D.  A maximum RPO of 60 minutes

Explanation:

Note that an option is not included in this list of options.

The complete list of options is:

A. A maximum MTTR of 30 minutes

B. A maximum MTBF of 30 minutes

C. A maximum RTO of 60 minutes

D.  A maximum RPO of 60 minutes

E. An SLA guarantee of 60 minutes

The Recovery Point Objective tells how old a backup file must be before it can be  recovered by a system after failure.

Since the data in the failover systems described in this question must be backup and recovered after the failure, it will be important to include the Recovery Point Objective (RPO) in the Business Continuity Plan.

Since the failover systems must use back up data that is no older than one hour, the backup of the system data must be done at intervals of 60 minutes or less. Meaning that the maximum RPO is 60 minutes.

Note that RPO is more critical than RTO in data backup

Following are the description of program

Answer:

Here is the sentinel-controlled while loop:

#include <iostream> //to use input output functions

using namespace std; // to identify objects like cin cout

int main(){ // start of main() function body

int test_score; // declare an integer variable for test scores

//prompts user to enter test scores and type-99 to stop entering scores

cout << "Enter the test scores (enter -99 to stop): ";

cin >> test_score; // reads test scores from user

while (test_score != -99){ // while loop keeps executing until user enters -99

cin >> test_score; } } // keeps taking and reading test scores from user

Explanation:

while loop in the above chunk of code keeps taking input scores from user until -99 is entered. Sentinel-controlled loops keep repeating until a sentinel value is entered. This sentinel value indicates the end of the data entry such as here the sentinel value is -99 which stops the while loop from iterating and taking the test score input from user.

The complete question is that the code should then report how many scores were  entered and the average of these scores. Do not count the end sentinel -99 as a score.

So the program that takes input scores and computes the number of scores entered and average of these scores is given below.

#include <iostream>  // to use input output functions

using namespace std;  // to identify objects like cin cout

int main(){  //start of main function body

double sum = 0.0;  // declares sum variable to hold the sum of test scores

int test_score,count =0;  

/* declares test_scores variable to hold the test scores entered by user and count variable to count how many test scores input by user */

cout << "Enter the test scores (or -99 to stop: ";

//prompts user to enter test scores and type-99 to stop entering scores

cin >> test_score;  // reads test scores from user

while (test_score != -99){  // while loop keeps executing until user enters -99

count++;  /* increments count variable each time a test cores is input by user to count the number of times user entered test scores */

sum = sum + test_score;  // adds the test scores

cin >> test_score;}  // reads test scores from user

if (count == 0)  // if user enters no test score displays the following message

cout << "No score entered by the user" << endl;

else  //if user enters test scores

//displays the numbers of times test scores are entered by user

cout<<"The number of test scores entered: "<<count;

/* displays average of test scores by dividing the sum of input test scores with the total number of input test scores */

cout << "\n The average of " << count << " test scores: " <<sum / count << endl;}

The program along with its output is attached.

Answer:

According to the principles of design, Repetition refers to the recurrence of elements of the design

One of the advantages of this is that it affords uniformity. Another is that it keeps the user of such a system familiar or with the interface of the operating system.

One major drawback of this principle especially as used in the question is that it creates a familiar route for hackers.

Another drawback is that creates what is called "repetition blindness". This normally occurs with perceptual identification tasks.

The  phenomenon may be  due to a failure in sensory analysis to process the same shape, figures or objects.

Answer:

Here is the function that returns the the smallest element in a list of integers

def indexOfSmallestElement(lst):

  smallest = lst.index(min(lst))

  return smallest

Explanation:

The function indexOfSmallestElement() takes a list of integers lst as parameter.

  smallest = lst.index(min(lst))

In the above statement two methods are used i.e. index() and min().

The first method index returns the index position of the list and the second method min() returns the minimum element of the list.

Now as a whole the statement min() first returns the smallest element in the list (lst) of integers and then the index() method returns the position of that minimum element of lst. At the end the index position of this smallest element in the list (lst) is stored in the smallest variable.

So lets say if we have a list of the following elements: [3,2,1,7,1,8] then min() returns the smallest element in this list i.e. 1 and index() returns the index position of this smallest element. Now notice that 1 occurs twice in the list and index() method only returns the the first index found in the list. So it returns the smallest index of the two index positions of 1 i.e 2. Hence the output is 2.

The test program is given below:

lst=list()  

num=int(input("Enter the list size: "))

print("Enter a list of numbers: ")

for i in range(int(num)):

  integers=int(input(""))

  lst.append(integers)

print("The index of the smallest element is: ")

print(indexOfSmallestElement(lst))

First the list named lst is created. After that the user is prompted to enter the size of the list which determines how many elements user wants to add to the list. num holds the size input by user. After that print statement displays the line"Enter a list of numbers: ". Next the for loop takes the integers from user num times. Suppose user want to enter 3 as list size then loop will take 3 elements from user. int(input("")) in this statement integer type input is taken from user using input() method. lst.append(integers)  statement is used to append these input integers into the list i.e. lst. print(indexOfSmallestElement(lst)) the statement calls the indexOfSmallestElement by passing lst to this method to return the index of the smallest element in the list of integers.

Answer:

Following are the description of the given points:

Explanation:

A) The Multiple greedy approaches could exist, which could be to reach for the closest emergency diamond, and yet clearly we are going to miss some very essential routes in that case. So, it can make every argument quickly, and seek to demonstrate a reference case for that.

B) An approach to the evolutionary algorithm and its users are going to just have states M x N. But each state (i, j) indicates the absolute difference between the amount of the selected diamond and the amounts of the costs incurred.

DP(i, j) = DimondVal(i, j) + max ((DP(i, j-1)-2), (DP(i-1,j-1)-3))

DP(i, j) is a description of the state.

DimondVal(i, j) is the diamond value at (i j), 0 if there is no diamond available.

This states must calculate the states of M N  and it involves continuous-time for each State to determine. Therefore the amount of time of such an algo is going to be O(MN).

Answer:

def random_marks(apostrophe, quotation, apostrophe_quotation):

   return "'"*apostrophe + "\""*quotation + "'\""*apostrophe_quotation

print(random_marks(3, 2, 3))

Explanation:

Create a function called random_marks that takes apostrophe, quotation, and apostrophe_quotation as parameters. Inside the function, return apostrophe sign times apostrophe plus quotation mark times quotation plus apostrophe sign quotation mark times apostrophe_quotation.

Note that plus sign (+) is used to concatenate strings. Also, if you multiply a string with a number, you get that number of strings ("#"*3 gives ###).

Then, call the function with given parameters and print

Question:

1. Open a command prompt window, type ipconfig/ all and press Enter.

2. Write down the information for your system’s active network connection(most likely either Ethernet or Wi-Fi).

* Physical address in paired hexadecimal form.

* Physical address expressed in binary form.

Answer:

00000000 11111111 00000011 10111110 10001100 11011010

Explanation:

(i)First, open a command prompt window by using the shortcut: Windows key + X then select command prompt in the list.

(ii)Now type ipconfig/ all and press Enter. This will return a few information

(a) To get the Physical address in paired hexadecimal form, copy any of the Physical Addresses shown. E.g

00-FF-03-BE-8C-DA

This is the hexadecimal form of the physical address.

(b) Now let's convert the physical address into its binary form as follows;

To convert to binary from hexadecimal, we can use the following table;

Hex                 |         Decimal                |           Binary

0                      |          0                           |           0000

1                       |          1                            |           0001

2                      |          2                           |           0010

3                      |          3                           |           0011

4                      |          4                           |           0100

5                      |          5                           |           0101

6                      |          6                           |           0110

7                      |          7                           |           0111

8                      |          8                           |           1000

9                      |          9                           |           1001

A                     |          10                           |           1010

B                      |          11                           |           1011

C                      |          12                           |           1100

D                      |          13                           |           1101

E                      |          14                           |           1110

F                      |          15                           |           1111

Now, from the table;

0 = 0000

0 = 0000

F = 1111

F = 1111

0 = 0000

3 = 0011

B = 1011

E = 1110

8 = 1000

C = 1100

D = 1101

A = 1010

Put together, 00-FF-03-BE-8C-DA becomes;

00000000 11111111 00000011 10111110 10001100 11011010

PS: Please make sure there is a space between ipconfig/ and all

Answer:

The program written in Python is as follows

nums = []

for i in range(0,68):

-->nums.append(i)

print(nums)

Explanation:

Please note that --> is used to denote indentation

The first line creates an empty list

nums = []

This line creates an iteration from 0 to 67, using iterating variable i

for i in range(0,68):

This line saves the current value of variable i into the empty list

nums.append(i)

At this point, the list has been completely filled with 0 to 67

This line prints the list

print(nums)

Answer:

Security controls are those measures taken to prevent, identify, counteract, and reduce security risks to computer systems, whereas, Security Requirements are guidelines or frameworks that stipulates measures to ensure security control.

Explanation:

Security controls encompass all the proactive measures taken to prevent a breach of the computer system by attackers. Security requirements are those security principles that need to be attained by a system before it can be certified as safe to use.

Security controls are of three types namely, management, operational, and technical controls. Examples of technical controls are firewalls and user authentication systems. A statement like 'The system shall apply load balancing', is a security requirement with an emphasis on availability.

Answer:

a. cd into the nested directories/ nested - level - 1 / directory using an absolute path

Explanation:

The directory is a location on the hard disk, which is also called a folder. It contains the files and also contains the other directories called sub directories.

A path to a file is merged with a slash and determines the file or directory in the operating system. An absolute path is the location file or directory from the actual file system

The directory's absolute path starts with a slash, and all slashed in the directory separates the directions.

All directions in the absolute path are written on the left side. The last name in the path may belong to the file, and the pwd command can determine the current directory.

The relative path is the location of the file. It begins with the working directory. An absolute path is unambiguous and working with deeply nested directories.

There are two commands which are used such as

We easily navigate the file system with the help of an absolute path.

Answer:

link encryption

Explanation:

In e-mail, SSL/TLS provides link encryption.

The SSL is an acronym for Secured Socket Layer and it is one of the secured way of authenticating and encrypting data between a computer and the mail server.

In the case of a TLS, it is an acronym for Transport Layer Security and it basically is used for providing authentication and encryption of data between two communicating systems on a network.

This ultimately implies that, SSL/TLS are standard network protocols that provides data integrity and privacy to users when communicating over the internet or networking devices as they're made to encrypt user credentials and data from unauthorized access. The SSL/TLS are an application layer protocol used for the encryption of mails sent over the internet, in order to protect user information such as username and password.

Answer:

Here is the modified DemoSalesperson2

public class DemoSalesperson2{ // class DemoSalesperson2

public static void main(String[] args) { //start of main() function body

SalesPerson[] sp = new SalesPerson[10]; // creates an array of SalesPerson object named sp

int start_id =111; // assign 111 to starting id number

double start_sal=25000; //assign 25000 to starting salary means salary will start from amount 25000

 for (int i =0; i<sp.length; i++) { //loop iterates until the value of loop variable i remains less then length of the array object sp

  sp[i] =new SalesPerson(start_id+i,start_sal+5000*(i)); /*at each iteration  ID number from 111 through 120 and a sales value that ranges from $25,000 to $70,000, increasing by $5,000 for each successive is displayed using object array sp[] which calls the SalesPerson constructor to access id and sales */

 System.out.println(sp[i].getId()+"   "+sp[i].getAnnualSales() );  } } } /*uses object sp of class SalesPerson to access the methods getId which returns the id and getAnnualSales method which returns the annual sales, to display id and annual sales */

Explanation:

The question first requires a SalesPerson class with these requisites:

Class name: Salesperson.

Data fields for Salesperson: int ID number , double annual sales amount.

Methods: constructor SalesPerson() that requires values for both data fields, as well as get and set methods for each of the data fields.

So according to the complete question's requirement, I have implemented SalesPerson class:

public class SalesPerson {   // class name

//data members: integer type id variable and double type sales variable

   private int id;  

   private double sales;  

   public SalesPerson(int id_no, double annual_sales) {   //constructor that requires values for id and sales

       id = id_no;  

       sales = annual_sales;     }  

   public int getId() {   //accessor getId() method to get or access the value of id data field

       return id;     }  

   public void setId(int id_no) {   //mutator setId to set the value of id data field

       id = id_no;     }  

   public double getAnnualSales() {   //accessor getAnnualSales() method to get or access the value of sales data field

       return sales;     }  

   public void setAnnualSales(double annual_sales) { //mutator setAnnualSales to set the value of sales data field

       sales = annual_sales;     }  }

However you can use my DemoSalesperson2 application for your own SalesPerson class.

Now I will explain the working of for loop used in DemoSalesperson2

Iteration 1:

i=0

i<sp.length is true because length of sp[] is 10 so i<10

This means the body of for loop will execute.

The statement inside the body of for loop is :

 sp[i] =new SalesPerson(start_id+i,start_sal+5000*(i));

class SalesPerson constructor is used to access the data members of SalesPerson class

start_id = 111

start_sal=25000

start_id+i = 111 + 0 = 111

start_sal+5000*(i) = 25000 + 5000 (0) = 25000

The values 111 and 25000 are stored to sp[0] means at the first index of the sp array.

System.out.println(sp[i].getId()+"   "+sp[i].getAnnualSales() );  

This statement uses sp object to get access to the getId and getAnnualSales methods to print the id number and sales amount.

So the output at 1st iteration is:

111   25000.0

Iteration 1:

The value of i is incremented to 1 so now i = 1

i<sp.length is true because length of sp[] is 10 so i<10

This means the body of for loop will execute.

The statement inside the body of for loop is :

 sp[i] =new SalesPerson(start_id+i,start_sal+5000*(i));

class SalesPerson constructor is used to access the data members of SalesPerson class

start_id = 111

start_sal=25000

start_id+i = 111 + 1 = 112

start_sal+5000*(i) = 25000 + 5000 (1) = 25000 + 5000 = 30000

The values 111 and 25000 are stored to sp[1] means at the first index of the sp array.

System.out.println(sp[i].getId()+"   "+sp[i].getAnnualSales() );  

This statement uses sp object to get access to the getId and getAnnualSales methods to print the id number and sales amount.

So the output at 1st iteration is:

112   30000.0

The loop keeps iterating and the value of id is incremented by 1 and value of sales is increased by 5000 at every iteration.

This loop continues to execute until the value of i exceeds the length of sp array i.e. 10.

The values from iteration 1 to 8 following the above explanation are:

Iteration 1:

111    25000.0

Iteration 2:

112    30000.0

Iteration 3:

113    35000.0

Iteration 4:

114   40000.0  

Iteration 5:

115   45000.0  

Iteration 6:

116   50000.0                                                          

Iteration 7:

117   55000.0                                                                                                      

Iteration 8:                                                                                      

118   60000.0      

Iteration 9:                                                                                    

119   65000.0

Iteration 10:                                                                                    

120   70000.0

At iteration 11 the for loop body will not execute as value of i at 11th iteration is i = 10 and i<sp.length evaluates to false as i = sp.length because length of sp array is 10 and now the value of i is also 10. So the loop ends. Screenshot of the program and its output is attached.

Answer:

1. Divide each bonus by regular bonus apply this to all the data

2. In cell C11 write, "Average" press tab key on the keyboard and then select the range of the cells either by typing "C7:C10" or by selecting it through the mouse.

Explanation:

The average bonus multiplier can be found by dividing each bonus with the regular bonus applying this to all the data and then putting the average formula and applying it to the cells C7:C10.  

After dividing the bonus with regular bonus, in cell C11 write, "Average" press tab key on the keyboard and then select the range of the cells either by typing "C7:C10" or by selecting it through the mouse.

Answer:

The function can return multiple values and the function can return an object

Explanation:

The advantage of returning a structure type from a function when compared to returning a fundamental type is that the function can return multiple values and also the function can return an object

A function in a structure can be passed to a function from any other function or from the main function itself and the definition of a structure can be seen in the function where it is found

Answer:

Linked lists and arrays are both linear data structures but while an array is a collection of items that can be accessed randomly, a linked list can be accessed sequentially.

A sparse matrix contains very few non-zero elements. For example;

_                        _

|  0   0   3  0  6    |

|   0   5   0  0  4   |

|   2   0   0  0  0   |

|_ 0   0   0  0  0 _|

In the implementation of a sparse matrix, the following are some of the pros and cons of using a linked list over an array;

PROS

i.  Linked lists are dynamic in nature and are readily flexible - they can expand and contract without having to allocate and/or de-allocated memory compared to an array where an initial size might need to be set and controlled almost manually. This makes it easy to store and remove elements from the sparse matrix.

ii. No memory wastage. Since the size of a linked list can grow or shrink at run time, there's no memory wastage as it adjusts depending on the number of items it wants to store. This is in contrast with arrays where you might have unallocated slots. Also, because the zeros of the sparse matrix need not be stored when using linked lists, memory is greatly conserved.

CONS

i. One of the biggest cons of linked lists is the difficulty in traversing items. With arrays, this is just of an order of 0(1) since the only requirement is the index of the item. With linked lists, traversal is sequential which means slow access time.

ii. Storage is another bottle neck when using linked lists in sparse matrix implementation. Each node item in a linked list contains other information that needs to be stored alongside the value such as the pointer to the next or previous item.

Answer:

Internet backbone

Explanation:

The internet backbone is made up of multiple networks from multiple users. It is the central data route between interconnected computer networks and core routers of the Internet on the large scale. This backbone does not have a unique central control or policies, and is hosted by big government, research and academic institutes, commercial organisations etc. Although it is governed by the principle of settlement-free peering, in which providers privately negotiate interconnection agreements, moves have been made to ensure that no particular internet backbone provider grows too large as to dominate the backbone market.

Answer:

The Boolean value returned by that expression will be True

Explanation:

We have two logical statements in that expression:

Expression 1: (10 >= 5*2)

This can be read as: is 10 greater than or equal to 5 multipled by 2. This evaluates to true as 10 is equal to 5 * 2. Hence expression 1 returns true

Expression 2: (10 <= 5*2)

This can be read as: is 10 less than or equal to 5 multiplied by 2. This also evaluates to true as 10 is equal to 5*2. Hence expression 2 returns true.

Now between this two expression is the and operator which evaluates to true if and only if both logical expressions returnes true.

True and True ==> True

Since Expression 1 ==> True and Expression 2 ==> True

This means Expression 1 and Expression 2 ==> True which is the Boolean value returned by the statement

The value of the python expression ((10 >= 5*2) and (10 <= 5*2)) is True

The code will definitely return a Boolean value(True or False).

For the expression to be True , the two statements must be True. The AND gate returns True if the whole statement is True.

(10 >= 5*2) is True because 10 is equals to 5 × 2 = 10.

(10 <= 5*2) is True because 10 is equals to 5 × 2 = 10.

The two statements are True . Therefore,

True and True = True.
